CARITA BEACH, Indonesia -- A tsunami believed to be triggered by a volcanic eruption killed at least 222 people in Indonesia during a busy holiday weekend, sweeping away hotels, hundreds of houses and a group of people attending a beach concert. More than 800 were reported injured and 28 missing after the tsunami hit around the Sunda Strait on Saturday night, the Disaster Management Agency said.

The toll could continue to rise because some areas had not yet been reached.

Scientists, including those from Indonesia's Meteorology and Geophysics agency, said Sunday that the tsunami could have been caused by undersea landslides or those occurring above sea level on the Anak Krakatau volcano's steep outside slope following the eruption. The volcano's name translates to "Child of Krakatoa," a volcanic island formed over years after one of the largest eruptions in recorded history occurred at the Krakatoa volcano more than a century ago. The scientists also cited tidal waves caused by the full moon.
